XMG: Ryzen 4000 Series Will Use Socket AM4

Considering DDR5 and (most likely) PCIe 5 are going to be mass market in 2021, I don't think this comes as much of a surprise. XMG is a manufacturer of ultra high end laptops, including the Apex 15 which uses a Ryzen 3950X and a B450 motherboard, and this was posted about that laptop a couple of weeks ago on their Reddit thread. This also backs up AMD's claim that Socket AM4 would be supported through 2020.

I have a 3600 and it was a good price. I figure I can get a couple years out of it and when a much faster 4xxx chip falls in price due to it's replacement being out, I will snag one then. Assuming I still have a working board. It was really weird, I was gaming the night before and got up in the middle of the night and noticed it was not on. It would not power on, no led on or fans spin, nothing.

Considering that AMD has not yet completed the AGESA cycle for Ryzen 3000 I don't want to imagine when it will end for Ryzen 4000. It has always been the same, Ryzen / BIOS releases have been a disaster the first 6 months on 3 existing generations.

I can't really see myself not staying with this setup for years to come unless my motherboard implodes, as my X370 motherboard won't let the Ryzen 4000 series stretch its legs, plus my 3700X isn't a slouch in the efficiency and performance markets either. This is one of those times in the computer ecosystem where the CPU and motherboard really aren't the limiting factors going forward for home users for a while to come.

The Ryzen 3000 series and upcoming 4000 series are fast enough not to be bottlenecks as resolutions have shifted towards the more GPU limited 2560x1440 and 3840x2160. Video encoding and decoding has shifted to be GPU accelerated, and with more programs, especially games, actually taking advantage of the available CPU cores combined with APIs which have less CPU overhead, having the latest and greatest isn't necessary.

PCIe 3.0 x16 has enough bandwidth to not bottleneck a GPU until it is at least twice as fast as the 2080 Ti as benchmarks show there is no difference in performance between x16 and x8 with that GPU, and that's going to be years before that happens at the ultra high end, much less the middle and upper middle ranges, especially as ray tracing will continue to slaughter GPUs for a while as well.
